Beats Music streaming service launching January 21st

Beats Music, the streaming service run by Beats Electronics, will launch on January 21st.

The headphone company, run by music industry exec Jimmy Iovine and famous producer Dr. Dre, says all U.S. consumers can try the service for free and AT&T customers can download or stream unlimited music for $10 per month. For $15 a month, a family of five can access the service. The charge will be part of your regular monthly bill.

Beats Music will be available on iPhone, Windows Mobile, Android, PC and Mac, and eventually through set-top boxes and other Web-connected devices.

The unlimited downloads will allow you to listen to music offline, but the downloads expire and disappear when your membership ends.

To differentiate itself from rivals like Google Play Music All Access, Spotify, Rdio and others, Beats Music combines algorithms with specialized curated programming from "tastemakers." The service itself comes from "the trust that comes from excellent handpicked music with the personalization that knows you're an individual and that a handful of stations can't satisfy all listeners," says the company.
